Pumped energy storage system technology and its AC–DC
The basic operation principle of a pumped-storage plant is that it converts electrical energy from a grid-interconnected system to hydraulic potential energy (so-called ''charging'') by pumping the water from a lower reservoir to an upper one during the off-peak periods, and then converts it back (''discharging'') by exploiting the available
Optimization control strategy of pumped storage station in power
The pumped storage power plant is reliable and flexible, with the ability to adapt swiftly to load changes. When the storage station was previously operational, the load distribution between units did not always take into account the differences in operation characteristics between the units, which resulted in higher energy consumption during operation.

In pumped storage plant, a second reservoir is constructed near the water outflow from the turbine. When the demand of electricity is low, the water from lower reservoir is pumped into the upper (main) reservoir. This is to ensure sufficient amount of water available in the main reservoir to fulfil the peak loads.
